STORAGE-BATTERY JAR- Specification of Letters Patent.

Patented May 1, 1906.

To all whom it may concern.-

Be it known that I, ROGER M. NEWBOLD, a citizen of the United States, and a resident of Louisville, county of Jefferson, and State of Kentucky. have invented certain new and useful Im rovem'ents in Storage-Battery Jars, of which the following is a specification and which are illustrated in the accompanyin drawings, forming a part thereof.

The invention relates to jars for containing the elements and electrolyte of a storage or secondary battery, its object being to provide a closure for the jar which while being liq uid-tight is readily removable; and it consists in a jar having a closure in the form of a lid which slides within the walls of the jar and is provided with an expansible flange at its margins and similar flanges encircling the terminal apertures.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a central vertical section of a storage battery. Fig. 2 is a plan section on the line 2 2 of Fig. 1. Fig. 3 is a detail section on the line 3 3 of Fig. 2, and Fig. 4 is a plan view of the cover.

The jar 10 is of any desired form, bein shown as substantially s uare in horizonta section and having paral el side walls and ribs 11 upstanding from its bottom for separating the elements 12 of the battery.

The cover 13 is of such size that it makes a loose fit with the walls of the jar, and a continuous flange 14, referably of rubber, is secured to its up er i ace along its mar s and projects latera y therefrom, giving t e cover normally a greater area than the internal cross-sectional area of the 'ar. As the cover is fitted into the jar the ange 14 is forced back, and hence makes a close fit with the jar-walls. Each of the apertures formed in the cover 13 for the accommodation of the terminals '15 16 is surrounded b a collar 17, preferably of soft rubber, and aving an instanding flange 18, thus contracting the aperture to less diameter than the diameter 0 the terminal. As the cover is forced into the jar the terminals ass through the apertures, spreading the flan cs 18, and thereby securing a tight fit. As s own, the collars 17 are formed integral with the flange 14, although obviously this is not essential. At

19 is shown a plug placed at the center of the cover 13 and servin as means for giving access to the interior 0 the battery for the purposes of inspection and regulation.

As heretofore made the covers of batter jars have either been fitted loosely within t e jar or the joints have been made tight by the use of wax or similar material applied after the charging operation. When the cover is loose, there is apt to bean escape of the liquid contents of the jar, especially 1n railway service, and also due to the effervescing action which takes place as the batter becomes completely charged. The liquid eing acid,

its escape is injurious to any articles which may be adjacent to the battery and to the external metal parts of the battery itself and its connections. When a tight fit for the cover is secured by the application of a plastic material, the latter must be broken in order to 0 en the jar, and consequently its use is atten ed with considerableinconvenience and expense.

The ar-closure herein shown and described is permanent in its character. It is an integral structure not necessitating the use of askets or other seal, and, furthermore, entire y pre-.

vents the escape of the liquid contents of the ar.

I claim as my invention- 1. A batteryjar closure comprising, in combination, a ri 'd plate, and a soft flange projecting from t e margin of the plate and lnclined u wardly from the lane thereof, whereb t e flange presents a at face to the wallso the jar.

2. A battery-jar closure comprising, in combination, a 1'1 id plate having terminal a ertures, and sofit flanges projecting from t e margins of the plate and of the a ertures and being inclined upwardly from t e plane of the plate, whereby the flanges present a flat face to the walls of the jar and to the terminals.

3. A closure for battery-jars, comprising a substantially rigid plate having apertures for the battery-terminals, and soft-rubbcr flanges projecting beyond its margins and encircling the terminal apertures and projecting inwardly.

4. closure for battery-'ars comprising a substantially rigid plate aving apertures for battery-terminals, and. flanges projecting and projecting into the terminal apertures, beyond the margins of the plate'and encirsuch flanges being of material more flexible IO cling and ro'ectmg gnto th? terminall aperthan the plate. tures, sue anges elng o materla more 5 flexible than the plate.
